just recently my wifes laptop hasn't been charging.  the light on the charger's box turns off when we plug the charger into the laptop.  we then noticed that it sparks when we plug it into the laptop.  we have had problems with the motherboard and had it changed b4.  also the laptop does still work if you wondering, it just won't charge. we noticed this about a couple of hours from now, so up untill exactly a couple of hours ago the laptop was fine.  she has been on it alot recently and the laptop does get pretty hot.  the last time we went through dell for customer service it took us forever to get the motherboard replaced, and i don't want it to take forever again.  right now im just wondering if anyone has had this problem b4, if someone has, how they dealt with it........actually im looking for anybodys opinion right now, and hopefully it will help us..............................thanx
